On Sunday, just three months after its grand opening, the 11,424-square-foot Williamsburg dance club Output will officially debut its roughly 2,500-square-foot penthouse and rooftop bar. The underground party promoterReSolute will break in the space atop 74 Wythe Avenue, with Kiwi house DJ Recloose, along with resident talent, providing the soundtrack.

“It’s in the heart of Williamsburg with an amazing skyline view, and we have a feeling that we’re all going to [be] spending lots of time there this summer,” reads the ReSolute announcement. Plans for a penthouse and roof deck were included in the original Department of Buildings application filed by David Cutler, of Hustvedt Cutler Architects, in September of 2010.

Earlier this year, a source familiar with Output said that the rooftop area would operate under a separate lease than the main dance floor and an attached Soviet communist-themed ground level bar and restaurant, which soft opened last week. Representatives from Output did not immediately reply to an email request for comment. Sunday’s party kicks off at 2 p.m. and goes ’til 11 p.m.
